Weapon pieces, element materials, boss drops, and utility items — what each category does and where to farm it.
By Bloxron Editorial Team · Last updated
Overview
Materials unlock weapons, finish forge routes, and fuel rerolls. Farm them from chests, bosses, and events. The weapons guide covers which weapons need which drops.
Four Material Categories
| Category | Function | When you need it |
|---|---|---|
| Weapon Pieces | Unlock weapon types | First time you open a new weapon line |
| Element Rerolls | Roll passive Element buffs | Level 500+ — see Elements guide |
| Boss Materials | Unlock advanced weapons | ★★★ and ★★★★ weapons |
| Utility Materials | Rerolls and access items | Rerolls and boss access |
Weapon Pieces
| Type | Unlocks |
|---|---|
| Sword Pieces | Sword weapon line |
| Katana Pieces | Katana weapon line |
| Buster Pieces | Buster weapon line |
Drop locations are on the bosses guide. See the weapons guide for which line you are building.
Elements & Element Rerolls
Character Elements (Fire, Thunder, Wind, Life, Earth, Water) are passive combat buffs rolled with Element Reroll items at level 500. They stack and are separate from weapon crafting materials.
Tier list and stacking rules are on the Elements guide. Boss drop rates are on the bosses guide.
Boss Materials
| Material | Used for |
|---|---|
| Sacrifice Piece | Dragon Slayer and other top-tier Buster paths |
| Moon Piece | Moon Cut katana evolution |
| Holy Material | Excalibur sword forging |
Where to farm
Boss-specific drop tables and respawn timers are on the bosses guide. Sacrifice Piece comes from Guts on Eclipse Island; Moon Piece from Nidavellir raids.
Utility Materials
| Item | Function |
|---|---|
| Race Reroll | Change character race (usable at Lv.500) — see Races guide |
| Element Reroll | Change elemental affinity |
| Blessing Reroll | Re-roll passive bonuses (usable at Lv.1000) — see Blessings guide |
| Boss Key | Access locked boss encounters |
| Boss Coin | Exchange for boss rewards |
None of these raise raw damage directly, but rerolls and boss access save time on the way to your target weapon.
FAQ
What are materials used for in Broken Blade?
Unlocking weapons (weapon pieces), crafting and forging (boss and element materials), and rerolls (Race, Element, Blessing). You need specific materials at each step — they are not optional side loot.
How do you get weapon pieces?
Chests, regular enemy farming, and boss encounters. Sword, Katana, and Buster pieces are separate — you only need the type matching the weapon line you are pursuing.
What is the difference between Elements and boss materials?
Elements (Fire, Thunder, Wind, etc.) are passive buffs from Element Rerolls — see the elements guide. Boss materials (Sacrifice Piece, Moon Piece, Holy Material) are crafting drops that unlock specific weapons like Excalibur, Moon Cut, and Dragon Slayer.
Do utility materials increase combat power?
No direct damage boost. Reroll items change your race, element, or blessing. Boss Key and Boss Coin open encounters that drop crafting materials.
